67-277 50mm Dia. UVFS Aspheric Lens; EFL=50mm; NA=0.5 VIS 425-675nm
This is the 67-277 model from Edmund Optics, a 50mm Dia. UVFS Aspheric Lens with an effective focal length (EFL) of 50mm and a numerical aperture (NA) of 0.5. The lens is designed for the visible light spectrum, specifically for wavelengths between 425nm and 675nm.
The lens is made of syn hpfs7980 corning, a high-performance fused silica material known for its excellent transmission properties and durability. The aspheric design of the lens helps to reduce spherical aberration, improving the overall image quality.
The lens has a diameter of 50mm and a thickness of 3.49mm at the edge, with a center thickness of 19.5mm. The inner and outer radii are 0mm, and the lens has a base shape of a circle.
The front and back of the lens are coated with edm vis 425-675nm, a coating that enhances the lens's performance in the specified wavelength range. The lens's geometry includes a range of parameters (k1, k2, r1, r2, bfl) that define its optical properties.
The lens is currently in stock and available for purchase through the Edmund Optics website.
